GDB claims to be changing the value of the variable 'x',
but the program doesn't seem to notice. When GDB exits,
it reports failure to close the image file.


File test.c:
------------
#include <stdio.h>

int x = 1;

int main(void)
{
  printf("test.c: x = %d\n",x);
  return 0;
}

--------------
gcc -g test.c
gdb a.out
(gdb) p x
$1 = 1
(gdb) set var x = 100
(gdb) p x
$2 = 100
(gdb) r
Starting program: c:/jsc/runtime/a.out
test.c: x = 1
(gdb) q
warning: cannot close "c:/jsc/runtime/a.out": Permission denied (EACCES)
